From time-to-time, your conservatory will need to be cleaned. This is a time-consuming job that requires specific expertise – so you’ll need to engage the services of a professional conservatory cleaning company to complete the work for you.

We’ve included some general tips in this FAQ section, so you can spot signs that your conservatory is ready to be cleaned. This means you won’t end up instructing a conservatory cleaning contractor needlessly and spending your hard-earned money


Cleaning Your Conservatory: A Short Guide

Please use this guide as a checklist if you think your conservatory might need a clean.

General Cleaning

The roof and side frames of your conservatory should be washed down every four months with a soap water solution to remove grime and atmospheric deposits. Avoiding the use of solvent based or abrasive cleaners on the conservatory roof and frames, as these could cause damage to your extension that will be expensive to fix.


Your double-glazed conservatory products include an inbuilt drainage system, comprising slots within the thresholds that allow any water ingress to flow to the outside. To ensure an efficient system these slots must remain unblocked. Periodically remove dirt, clear drain holes and check drainage operation by flushing through with water.

Weather Seals

Ensure that the weather seals fitted to your conservatory doors and windows do not become dislodged during cleaning. If this occurs, slide the seal back immediately to avoid damage when the product is closed. If the weather seals are broken or damaged and draughts can be felt, contact your installer to arrange for a replacement.

Gutters & Box Gutters

In a conservatory the guttering is always laid level in accordance with BS EN 12056 Parts 1,3 & 5 Code of Practice for Drainage of Roofs. Therefore, you will notice standing water in your gutter system. It is important that you clean the gutters on a regular basis – be sure to use crawl boards so safety reasons when accessing a conservatory roof.

Don’t Use a Power Washer

It’s tempting to use a power washer to blast unsightly grime off your conservatory, but we would not recommend using one.  This type of device uses a tremendous amount of force, which could cause damage to your structure.

It’s not uncommon for the force of a power washer to dislodge tiles from the roof of a conservatory. This will be an expensive problem to fix, so make sure your conservatory cleaning contractor uses a less intrusive method.

Prevent the Build-Up of Moss

The spread of unsightly moss will disrupt the appearance of your conservatory and make it look unsightly. You can stop this from happening by using a chemical solution after you’ve swept and washed the area in question.

You should apply this same methodology to the inside of your conservatory, which also needs to be properly maintained. If mould is present, you may have a ventilation problem, in which case you’ll need to seek further advice.

Ventilating a conservatory can be achieved by installing fans, or by updating your old roof with an Ultraframe one that includes trickle vents as standard. Trickle vents act as an essential release point for warm moist air.

Opening your windows will naturally ventilate your room, and you can maximise this effect by replacing your existing ones with a tilt and turn design that’ll catch side breezes and redirect them inside your conservatory.

The inclusion of bi-fold or sliding patio doors will ensure a healthy induction of natural air into your room, while also providing a range of other welcome benefits – like improved access and better views of your much-loved garden.

Finding the Right Conservatory Cleaning Company

These companies can offer a 'deep' clean of your conservatory and may even clean the gutters. Always make sure you agree with them what is/isn't covered before you engage them. Please see our generic guidelines here for cleaning and maintenance – use it as a checklist to make sure your cleaning company does the job right.
